[QUOTE="Umbra, post: 8405054, member: 658055"] I think you're right. I've got those very subs sitting on a shelf. They look like 12's to me, but OP, just measure the diameter of the cone to be sure. The newest model has a smaller logo centered on the dustcap. On the previous model the logo encompassed the whole front of the cone. Here's their line: [URL="http://www.memphiscaraudio.com/products/subwoofers/power-reference-subwoofers/"]Power Reference Subwoofers - Memphis Car Audio[/URL] Take note of the last four characters of the model numbers. The first two characters are the size of the cone. The third character is either an S or D for single or double voice coil respectively (yours is SVC unless there is a second pair of push terminals on the other side of the sub - can't tell from the picture), the last digit, 4, means the voice coils are all 4 ohms. As far as the amp goes there's got to be a model number somewhere, but if you can't find that photographing or listing the blade fuse ratings will give us an idea of its output. [/QUOTE]
